Superheavy dark-bright soliton as a signature of spatial symmetry breaking transition in harmonically trapped Bose mixtures
Zheng Gao, Ling-Zheng Meng, Jie Liu +1
We investigate the dynamics of a dark-bright soliton in harmonically trapped two-component Bose-Einstein condensates and reveal an interesting spontaneous spatial symmetry breaking…

Controllable Thouless Pumping Switching Dynamics of Gap Solitons Mediated by Finite Bogoliubov Excitations
Tao Jiang, Jie Liu, Li-Chen Zhao
We investigate the Thouless pumping dynamics of nonlinear gap solitons and attempt to realize topological Chern number switching by modulating nonlinear parameters and varying the…
